Levothyroxine is considered the gold standard for hypothyroidism treatment. Experts consider levothyroxine to be the first-choice medication for treating hypothyroidism. This is because it works well and doesn't have too many side effects. Levothyroxine is generally preferred over medications like Armour Thyroid.
However, without thyroid replacement medication, a person with overt hypothyroidism cannot function optimally and will suffer from the physical and mental symptoms of hypothyroidism. The half-life of levothyroxine is 6-7 days, which means it takes about 4-5 weeks for your body to rid itself of levothyroxine.
IBSA Pharma Inc is voluntarily recalling more than 2 dozen lots of Tirosint-SOL (levothyroxine sodium) oral solution because the medication may be subpotent. The recall appeared in the March 1, 2023, US Food and Drug Administration (FDA) Enforcement Report.

Hypothyroidism can affect the heart and circulatory system in several ways. Lower production of thyroid hormone slows your heart rate. Hypothyroidism also makes the arteries less elastic, and blood pressure rises in order to circulate blood around the body.
